Heatuneed is built to make one job easier: turn a room survey into a clear heating calculation and a report you can share.

Walk through each room once and Heatuneed captures the dimensions of its walls, windows, doors, floor, and ceiling. Those measurements feed the heat-loss calculation directly, so you do not have to measure and enter every room element by hand.

What Heatuneed Helps You Do

Measure the Room

• Capture a dimensioned 3D model as you walk through the space
• Detect walls, windows, doors, floors, and ceilings
• Identify radiators and keep each room organized within its project
• Review the room model before starting the thermal analysis

Calculate Heat Loss and Heating Needs

Heatuneed turns the measured room into figures that can guide a heating decision:

Room heat-loss and heating-demand results created from the measured room model.

• Calculate the design heat load in kW and energy demand in kWh
• Use the building’s design heat load as the starting power requirement for sizing a heat pump or boiler
• Break down losses through walls, windows, doors, floors, and roofs
• Model boundaries to outside air, the ground, adjacent rooms, and unheated spaces
• Apply construction details, thermal properties, U-values, and orientation

Check the Radiators

Heatuneed compares the heating requirement with the available radiator capacity. This helps you see which radiators are large enough and where a sizing recommendation needs attention.

Create a Report

Review the results, then export a Simple or Complete PDF for a client, contractor, or project file. You can view the sample reports before the app is released.

Who Benefits from Heatuneed?

Heating Professionals

Turn room geometry into design heat loads, radiator requirements, and reports for heating projects.

Property Managers

Keep room surveys, assumptions, and results together while planning heating or envelope improvements.

Homeowners

Understand how a room loses heat and whether its radiators meet the calculated requirement before planning a renovation.

The Workflow

1. Scan the room: Walk through the space while Heatuneed captures its geometry.
2. Review the model: Check the detected surfaces, openings, dimensions, and radiators.
3. Describe the building: Set the construction details, U-values, and boundary conditions.
4. Analyze the room: Review its heat load, energy demand, element losses, and radiator capacity.
5. Share the result: Preview and export a Simple or Complete PDF report.

The Technology Behind the Workflow

Heatuneed uses Apple RoomPlan and the LiDAR Scanner to create the measured 3D room model. Creating a scan therefore requires a supported LiDAR-equipped iPhone or iPad. See the current compatibility list before planning a survey.

The technology supports the workflow; the outcome is the important part: room measurements, heating calculations, radiator checks, and reports in one project.

App Availability

Heatuneed is not available on the App Store yet. You can still explore the compatibility requirements, sample reports, and free heating calculators on this website while the app is being prepared for release.
